SUMMARY

To find the values of B and C in a partial fractions equation, one can utilize the method of equating coefficients after expanding both sides of the equation. The discussion highlights that while A can be determined by substituting specific values for x, B and C can be isolated by manipulating the equation and applying the power of x. The provided resource offers additional insights into the process of solving partial fractions.

Hey guys, I have a quick question concerning partial fractions, say i have the values A(..)+B(..)+C(..) and i can only get A b substituting a value for x, but I can not make A or C go zero or A and B go to zero at the same time, if you understand ? How do I get the values B and C ? I remember there was a way using the power of x on each side ? Thanks in advance.
